It's moments like these that have made London Fashion Week 2014 so exciting.

We've already celebratedthe return of Burberry this week, and it’s easy to get wrapped up in who’s front rowing at which shows and which designers are getting the Anna Wintour seal of approval, but London Fashion Week is about much more than that. In the true spirit of British eccentricity LFW is always responsible for some weird, wacky and downright wonderful moments.

Cara Delevingne joined her best pal Rita Ora on-stage at the DKNY Art Works party, which the Burberry model hosted on Wednesday night (June 12, 2013). Iggy Azalea and Wretch 32 had entertained the crowds at the Old Firestation on Lambeth High Street, though it was Rita's duet with Cara that really raised the roof.

Cara showed off her dance moves and rapping skills on a rendition of Notorious BIG's 'Juicy' - and, well, they weren't half bad. The model wore a black jumpsuit with elaborate jewellery and high top sneakers, while pal Rita opted for a blue and black top with black skirt.

Billboard chart-topper Rihanna is making the foray into the worlds of beauty, fashion and television by hosting her own reality show that challenges designers to make outfits for celebrities. Sound a bit too much like Project Runway? Well, that's because it is, but then there's the celebrity thing. Of course.

Premiering in late 2013, 'Styled to Rock' will see 12 aspiring designers handpicked by the Grammy-award winner. They will be tasked with styling a celebrity guest on each episode (don't tell us: Katy Perry?) with Rihanna and the VIP choosing who should progress to the next round. "Fashion has always played an integral part in my life and career. I am so excited to partner with Style Network and share my creative insight with these 12 designers and give them this opportunity to showcase their work," Rihanna, 24, said in a statement. The series will be a version of the show of the same name that the singer road-toasted over the summer. Airing on Sky Living, that show featured Pussycat Dolls star Nicola Roberts, British fashion designer Henry Holland and Rihanna's stylist Lysa Cooper.

Despite her recent Billboard chart success with Unapologetic, it appears Rihanna is continuing to spread her wings in the entertainment industry and it's not difficult to envisage her filling a similar role to Tyra Banks and Heidi Klum on their respective model and fashion reality shows.

Though most of the group partied until the early hours, the scrappy young Harry Styles left early in a Range Rover. To be fair to the One Direction singer, he’s had a pretty busy week attending the various shows at London Fashion Week. He took up a front row seat for the Burberry Spring/Summer 2013 catwalk collection, though hardly sounded specialist on the subject of women’s fashion when quizzed by the Press Association. “I like coats and it's cold so they always have to wear coats, so it's great,” he said, adding, “I thought the show was great. I liked the colours - they're not too much, they're quite subtle. I think their winter stuff's wicked.” So he basically likes the coats and the colours.
